Login does not succeed – identification problem message:

“Login unsuccessful. Please check your UserID and password and try again. Tip: Please check the case of the letters you typed, and whether you inserted spaces or tabs. If the problem persists, contact your administrator.”

Cause of the Problem:

UserID or password are wrong.

Solution:

• Check Caps-Lock:
  Check that the Caps-Lock key is not on, press Caps-Lock and see if a light on the right of your keyboard goes off
  
  
• Check multi-lingual Windows:
  Does the operating system you are using support other languages? Can you type languages other than English, like Spanish, on your computer? If it does, check that you are typing in English before you type your UserID and password.
  
  
• Enter the password manually:
  Type in the password manually. Do not copy and paste it from the invitation, because copying the password may copy extra characters with it.
